DESCRIPTION

The M74HC374 is an high speed CMOS OCTAL

D-TYPE FLIP FLOP WITH 3-STATE OUTPUTS

NON INVERTING fabricated with sub-micron

This 8 bit D-TYPE FLIP FLOP is controlled by a

clock input (CK) and an output enable input (OE).

On the positive transition of the clock, the Q

outputs will be set to the logic state that were

setup at the D inputs.

While the OE input is at low level, the eight outputs

will be in a normal logic state (high or low logic

level) and while OE is high the outputs will be in

a high impedance state.

The output control does not affect the internal

operation of flip-flops; that is, the old data can be

retained or the new data can be entered even

while the outputs are off.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
